BMW already considering four cylinders for next M3

The cylinder count in BMW's M3 has fluctuated over the years. The original M3 debuted in 1985 packing a 2.3-liter inline-four, but subsequent models went with sixes until the outgoing generation upped the cylinder count to eight. With its latest model, BMW has dropped back to six cylinders with a pair of turbos taking the place of the extra pistons. But the next M3 sedan and M4 coupe could go back to the model line's roots with a four-cylinder engine.
Speaking with BMW M product manager Carsten Pries at the launch of the latest M3 and M4 in Portugal, our Aussie compatriots at Motoring.com.au report that "you could see a future [M3] powered by a four-cylinder engine." Offsetting the reduction in cylinders, the lighter engine would benefit the vehicle's weight and balance, thus enhancing performance.
We wouldn't expect the next M3 and M4 to lose any power in the process, though: Output in the M3 has only risen over the generations, from 192 horsepower in the four-pot original to 282 hp in the six-cylinder E36, 338 hp in the six-cylinder E46, 414 hp in the V8 E90 and 425 ponies in the new turbocharged six-cylinder F80 model. With that latter model having just debuted, it'll likely be a good six or seven years before the next version comes along, giving BMW plenty of time to settle on an engine - however many cylinders and turbochargers it has. In the meantime, you'll have to forgive us for taking a romp down M3 memory lane in the fresh gallery of images above.

Watch the BMW i8 get wrung out on the Ring

Been wondering where the heck the reviews of the all-new, plug-in-hybrid BMW i8 have been? After all, the car isn't exactly new, having debuted in concept form way back in September of 2009. In August of last year, we even tested a prototype of the new supercar. Despite that, though, we still haven't gotten a crack at the actual vehicle that will be sold to the public.
Well, we're happy to tell you that we're currently testing the i8 and will have a proper review for you soon. If, however, you're just aching for some coverage of the low-slung plug-in, we have a short video of it in action around Germany's famed Nürburgring.
Despite it's three-cylinder, turbocharged gas engine, the i8 sounds pretty angry as it laps the Ring. That is, until it has a little bit of a breakdown. According to the guys that caught the car on video, it appeared the i8 had a minor brake issue, and was parked on the side of the track for a good 15 minutes, with the driver pumping the brakes. We should probably just take this as proof, then, that manufacturers are actually using the Ring for testing, and not just messing about.

BMW 1 Series GT morphs into production-spec 225i Active Tourer

Based on the effort - and money - BMW is spending to break off the coupes and convertibles in its lineup as even-numbered models (like the new 2 Series and 4 Series), we figured the production version of the 2012 Concept Active Tourer was a lock to wear the 1 Series GT name. These spy shots paint a different picture, however, as they show the car seemingly in full showroom-ready trim during a photo shoot, wearing the 225i name indicating that it will be in the 2 Series family.
While it's still very possible that this badging is the final bit of trickery for disguising the front-wheel-drive 1 Series GT, the hatchback itself appears to be the real deal. Aside from new fascias, a smaller grille and slightly different lights, the styling of this "225i" stayed pretty true to the Concept Active Tourer. Thanks to our long-lensed photographer, we also get a brief glimpse inside the hatchback, which reveals a two-tiered instrument panel layout including the free-standing navigation display that is similar to the concept car.
Regardless of what name this new model will wear, expect it to be unveiled at next year's Geneva Motor Show in March before arriving in the US sometime in 2015.
